A few years ago we saw a trial under way at the Organic Garden at Yalding, Kent, then run by Henry Doubleday/Garden Organic - a lot of outdoor tomatoes with clear plastic sheeting over the top, to see if the plastic would protect against blight. Does anyone know the outcome? I imagine the plastic would keep the rain off well enough, but suspect the atmosphere under the plastic could get very humid, and therefore might provide ideal conditions for blight to thrive.

I have no idea, but you could try an email asking them perhaps Ken ?

Ken
I would have thought you are right but they must have reasons for their experiments.

Years ago KG ran an article on an Italian man who had an allotment in London and he successfuly grew all Italian types of veg. His tomatoes were grown outdoors with a sheet of polythene suspended over them and, if I remember corectly, he never had trouble with blight.
